B TERMINAL CIRCUIT
Description
INFOID:0000000005272444
The terminal “1” (B) circuit supplies power to charge the battery and operate the vehicles electrical system.
Diagnosis Procedure
INFOID:0000000005272445
Regarding Wiring Diagram information, refer to
1.
CHECK TERMINAL “1” CONNECTION
1.
Turn ignition switch OFF.
2.
Verify terminal “1” is clean and tight.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> Repair terminal “1” connection. Confirm repair by performing complete Starting/Charging system
test. Refer to diagnostic station instruction instruction.
2.
CHECK TERMINAL “1” CIRCUIT
Check voltage between generator connector E206 terminal 1 and
ground.
Is voltage reading as specified?
YES
>> GO TO 3.
NO
>> Check harness for open between generator and fusible
link.
3.
CHECK TERMINAL “1” CONNECTION (VOLTAGE DROP TEST)
1.
Start engine, then engine running at idle and warm.
2.
Check voltage between battery positive terminal and generator
connector E206 terminal 1.
Is the voltage reading as specified?
YES
>> Terminal “1” circuit is normal. Refer to
NO
>> Check harness between battery and generator for high resistance.

L TERMINAL CIRCUIT
Description
INFOID:0000000005272446
The terminal “2” (L) circuit controls the charge warning lamp. The charge warning lamp illuminates when the
ignition switch is set to ON or START. When the generator is providing sufficient voltage with the engine run-
ning, the charge warning lamp will go off. If the charge warning lamp illuminates with the engine running, a
malfunction is indicated.
Diagnosis Procedure
INFOID:0000000005272447
Regarding Wiring Diagram information, refer to
1.
CHECK CHARGE WARNING LAMP CIRCUIT CONNECTION
Verify generator connector E205 terminal 2 is clean and tight.
Is the connection secure?
YES
>> GO TO 2
NO
>> Repair the connection. Confirm repair by performing complete Starting/Charging system test.
Refer to diagnostic station instruction instruction.
2.
CHECK CHARGE WARNING LAMP CIRCUIT
1.
Disconnect generator connector E205.
2.
Apply ground to generator harness connector E205 terminal 2
with the ignition switch in the ON position.
Does the charge lamp illuminate?
YES
>> Check generator function. Refer to
NO
>> GO TO 3
3.
CHECK HARNESS CONTINUITY
1.
Turn ignition switch OFF.
2.
Disconnect the combination meter connector M24.
3.
Check continuity between generator harness connector E205 (A
)terminal 2 and combination meter harness connector M24 (B)
terminal 2.
4.
Check continuity between generator harness connector E205
(A) terminal 2 and ground.
Are the continuity results as specified?
YES
>> Replace the combination meter. Refer to
IP-11, "Removal and Installation"
NO
>> Repair the harness or connector.
Charge lamp should illuminate

S TERMINAL CIRCUIT
Description
INFOID:0000000005272448
The output voltage of the generator is controlled by the IC regulator at terminal “3” (S) detecting the input volt-
age. Terminal “3” circuit detects the battery voltage to adjust the generator output voltage with the IC regulator.
Diagnosis Procedure
INFOID:0000000005272449
Regarding Wiring Diagram information, refer to
1.
CHECK VOLTAGE REGULATOR CIRCUIT CONNECTION
Check to see if connector E205 terminal 3 is clean and tight.
Is the inspection result normal?
YES
>> GO TO 2
NO
>> Repair terminal connection. Confirm repair by performing complete Starting/Charging system test.
Refer to diagnostic station instruction instruction.
2.
CHECK VOLTAGE REGULATOR CIRCUIT
Check voltage between generator harness connector E205 terminal
3 and ground.
Does battery voltage exist?
YES
>> Refer to
.
NO
>> Check harness for open between generator and fuse.
